目的 :探讨内侧型蝶骨嵴脑膜瘤手术治疗方法。方法 :本文复习了 2 0例内侧型蝶骨嵴脑膜瘤的临床资料 ,重点讨论了手术方法。结果 :实现脑膜瘤镜下全切 17例 ,大部分切除 3例 ,无手术死亡 ,疗效满意。结论 :认为在熟悉掌握毗邻显微解剖结构的基础上 ,采用显微外科技术 (CUSA) ,结合术前超选栓塞颈外动脉系统的肿瘤供应支 ,可提高肿瘤全切率 ,减少对周围重要神经结构的损伤 ,降低死亡率。但对明显侵犯下丘脑、海绵窦等重要结构的肿瘤 ,手术难度较大者 ,尚应考虑姑息的手术方式 Objective: To investigate the surgical treatment of medial sphenoid ridge meningioma. Methods: This review of 20 cases of medial sphenoid ridge meningioma clinical data, focusing on the surgical approach. Results: Mesenteric endoscopic total resection in 17 cases, most of the resection in 3 cases, no operative death, the effect is satisfactory. Conclusion: Based on familiarity with adjacent microanatomical anatomy, using microsurgical techniques (CUSA) combined with preoperative superselective embolization of the tumor supply branch of the external carotid artery system can increase the rate of tumor resection and reduce the importance of the surrounding area Nerve structure damage, reduce mortality. However, significant violations of the hypothalamus, cavernous sinus and other important structures of the tumor, surgery is more difficult, should consider palliative surgery
